Diemaco SA20 Staked buffer tube

[klatham]

Hi all,

I picked up an A2 stock kit for my SA20 and when I got my rifle, I noticed that the castle nut is staked to the receiver end plate. Any ideas how to remove this without damaging anything too badly? Should I try to drill it out somehow?

Thanks!

Done it a few times and the best method which is also common practice on the ar15 forums.

Use a punch to push back the displaced metal of the end plate then with a castlenut wrench and the lower on a block vised...twist the nut off.

Take the pistol grip off and hold the lower by where the grip fits. Use a mullet to strike the wrench.

One of these GT? LOL

Best typo ever

Don't under estimate the power of mullet!!!

Sounds fishy... I pictured the OP hammering away with one of these...

That rifle does not use a castle nut. If you don't cut the staking, you will break things.

Why do you need to remove it?

It would appear he intends to make a C7A1 clone out of it.

What kind of nut does it use then?

He wants to remove the buffer tube nut (castle nut) so he can remove the buffer tube, and replace it with a different buffer tube that works with a fixed stock.

Here's the pics of the nut. (buffer tube retaining nut?)

When I was issued a C7, it had a fixed stock, so I am kind of going for the nostalgia factor.

Perhaps it's an overly simple question, but I am reluctant to permanently damage my rifle.

You just remove that bit of staking material that got pushed into that indent. Hammer and little chisel/punches will do the trick.

If you get it off without damaging the parts, I am interested in buying the receiver extension, end plate and nut. PM me if you wish to sell.

That rifle uses a castle nut. Take a look at the pics. I think your confused between the fixed stock model.

This is a castle nut.... The one pictured above is not a castle nut.

A "dimple nut" perhaps? Lol

 

[fenceline]

Funny, they both require castle nut wrenches......

Geez, worse than taking a Norc apart.

Nope, different wrenches.
